Question

我想把标签放在情节上。我的代码就像

import matplotlib.pyplot as plt
x1 = [1,2,3,4,5,6,7,8,9,10]
x2 = [7,3,2,4,1,4,3,5,8,4]
y  = [0,1,1,0,1,0,0,1,0,1]
plt.scatter(x1,x2,c=y)
plt.show()

输出：

我想在图表上添加图例标签 0 和 1 。如果标签是假的还是真的，它的好处是什么？

如果答案没有任何迭代，我们将不胜感激

Answer 1

原则上，matplotlib scatterplot with legend或Matplotlib scatter plot with legend等问题会显示如何获取散点图的图例。

由于您明确要求不进行迭代，您当然可以通过映射替换迭代。

请注意，这是一个纯粹的学术示例，使用for循环要容易得多。
